Cool John... let us know what you go with and how it turns out.

(another Edit): I'm actually a little surprised he went with the 042. If you run a search for the 044, it's been mentioned in here a bit.

 

Considering that your stock cam is a (196/207 .479/.467 115), I think that anything less than the Comp 206/212 would be a waste of time, energy, and money. The Vinci 042 (200/208 .500/.500 115) isn't really even an upgrade. I think the 206/212 is ideal if you want to tow, but of course, you should get more input from Comp first.

 

I admit that I do like the sounds of the 206/212.

I didn't have any luck talking with my particular guy from Comp. I told him that I wanted a torque cam I could drop in a stock motor. He kept pointing me to cams like the 212/218 (not that that's bad), and telling me to throw coverters and headers at the truck first. That's really not what I was looking for. I didn't want to "need" to have those parts - I simply wanted those parts to compliment the cam afterwards. He was telling me I need to build the motor first.

When I asked about the 206/212, he told me to put my stock cam back in because it wouldn't be worth it.

They basically turned me away.

Just because the Comp guys don't have a clue about the value of the 206/212 doesn't mean that the cam isn't any good and you shouldn't buy it. I think the 206/212 is a great cam, it would be perfect for me if the lifts were more like 550-560 (since I have a blower). Instead, I am looking at the Comp 208/214, 554/559, 115 (since it has higher lift than the 206/212), and also a cam from another manufacturer that is close to ideal at 205/211, 550/544, 114. For a N/A application, I would jump on the 206/212 in a heartbeat.

I do not want an aftermarket converter, and want to retain my full towing capacities. From all the people I've talked to (and I've talked to a LOT of people - not just people who make cams, but people who build motors for trucks), it sounds like anything OVER 206/212 is going to ensure a torque lag down low, perhaps until 1800-2000 RPM's. So given my reluctance to change my stock TC, I am leaning heavily toward the 205/211 with the decent lift, to give my blower some nice cavities to pump the air into...

 

I hear you... I was ready to order the cam right then and there, but the guy was hell-bent on quarter mile times, which isn't my only goal. I called another shop (sponsor), and they talked me away from the 206/212 also. They were very helpfull, but I really wanted to hear about the 206/212. I just got frustrated and dropped it.

When I initially installed the 210/218, I felt it go a little soft under 1,500. I spend a few hours last night making some VE changes from 400-1600 last night, and have felt a "refining" of that area. I'm waiting for my fuel trims to settle out before I actually say I'm onto anything solid, but initial impression is that I cleaned up the power under 1,600 enough to pull seamlessly off idle with the stock 'verter.

I too am real picky about the stock coverter powerband thing, but I can honestly say that even before the above tweaks, the powerband was perfectly liveable. I understand the 5.3 will be a little more sensitive, so that 'over' 206/212 thought sounds pretty legit.

 

Yeah, you've got more latitude with the LQ9, you've got 65 more FWHP to start with (the LM7 in 2003 only had 285 FWHP ). And a lot of your power is probably down low, so you will more than likely be very cool with the 210/218. But now you've got me thinking about that 208/214 again...

 

Sorry!

 

Mmm hmm, I bet you are....

 

Is a cam swap as noticable of an improvement as a good tune??-BJ
